Abstract

PMA-SiO2: Heteropolyacid Catalysis for Michael Addition-Convenient Route to Substituted-3-Indoles

Author(s): Vijay Kumar Pasala

Synthesis of 3-substituted indoles in a hassel-free, ecofriendly manner by treating indoles with α, β-unsaturated carbonyl or nitro compounds under acidic conditions to give good to excellent yields with shorter reaction durations are described. The catalyst is recyclable for three to four times without great loss in the activity.
